A changeable critical state for a switchable photocurrent direction <i>via</i> the photo-electrochemical photocurrent polarity switching effect in BiFeO₃ nanoparticulate films.

ABSTRACT: The photoelectrochemical photocurrent switching (PEPS) effect to change the photocurrent direction from cathodic to anodic via external bias is an important phenomenon. Specifically, tuning the critical state or the potential corresponding to a switchable photocurrent direction through easily controllable parameters is crucial for developing efficient photo-electrocatalyst systems. Although the PEPS effect has been reported in quite a few recently published studies, the changeable critical state has not yet been demonstrated. In this study, for the first time, we present a photoelectrochemical (PEC) system based on bismuth ferrite (BiFeO₃) nanoparticulate films that demonstrates a changeable critical state controlled via the composition of an electrolyte medium.
